The present embodiment turns back capture unit 200 including reservoir block 210, intake elbow 220 and outlet bend pipe 230, described
Intake elbow 220 be connected with the bottom of outlet bend pipe 230 and constitute bend pipe of turning back, described reservoir block 210 is inclined
It is arranged on outlet bend pipe 230, the inclined bottom for being arranged at outlet bend pipe 230 of reservoir block 210, as shown in figure 1, reservoir portion
Part 210 is arranged at bend pipe bottom side to the right of turning back, and described reservoir block 210 is set to spheroidal so that fine particle one
Denier is into being just difficult to be flown out by reservoir block 210 after reservoir block 210, it is therefore prevented that the particle in reservoir block 210 occurs secondary
Airborne dust.
Particulate matter is settled and is stored in reservoir block 210 in bend pipe of turning back, and reservoir block 210 and vertical direction
Inclination angle is δ with the inclination angle of vertical direction for 10-30 °, the i.e. geometric center lines of reservoir block 210, δ=10-30 °, that is, is stored up
The angle of the upper end open and horizontal plane that integrate part 210 is 10-30 °, preferably 20 ° of the present embodiment.When flue gas and particulate matter are in folding
When bending pipe is moved, under the collective effect of gravity and inertia force, the particulate matter in flue gas can be deposited in bend pipe of turning back to particulate matter,
And the bottom of outlet bend pipe 230 is mainly gathered in, because the upper end open of reservoir block 210 and the angle of horizontal plane are 10-
30 °, particle, can directly by the upper end open first motion of reservoir block 210 in the bottom infall process of outlet bend pipe 230
Into reservoir block 210.
It is worth further illustrating, the minimum position of bend pipe radius of curvature of turning back is located at the bottommost of bend pipe of turning back, and
Reservoir block of the present utility model 210 is not arranged at the minimum position of bend pipe radius of curvature of turning back, but inclined is arranged at
On outlet bend pipe 230, the position is not the minimum position of radius of curvature, and reservoir block 210 is obliquely installed, and has broken the formula of turning back
Dust-precipitator capturing device is arranged on turn back bend pipe curvature minimum at or vertical lowest part inertial thinking, on the contrary to particulate matter
With preferably trapping and trapping effect.Its reason is probably, on the basis of the original initial velocity of the particle in flue gas, in gravity and
Under the collective effect of the inertia force in particle motion process, it is more easy to be gathered near the bottom of outlet bend pipe 230, the setting is caused
Particulate matter is easier to be settled in bend pipe of turning back and be stored in reservoir block 210.
The above-mentioned porch of reservoir block 210 is additionally provided with waterfog head 212, and particulate matter is by after water smoke moistening, storing up
Secondary agglomeration is carried out in collection part 210 so that fine particle carries out reunion and grows up, increases weight, it is to avoid be deposited in reservoir portion
The particulate matter of the bottom of part 210 flies into outlet bend pipe 230 again.And, it is provided with the bottom of reservoir block 210 and unloads dirt valve 213,
After a part of particle thing has been preserved in reservoir block 210, can open and unload dirt valve 213, will accumulate in reservoir block 210
Grain thing discharge.
Above-mentioned intake elbow 220 and outlet bend pipe 230 are connected by shaking bellows 201 with flue, i.e. air inlet
The flue gas at the top of bend pipe 220 flows into end 221 and is connected with the flue on top by shaking bellows 201, and outlet bend pipe 230 is pushed up
The flue gas outflow end 231 in portion is connected by shaking bellows 201 with the flue on top, that is, bend pipe of turning back can be relative to flue gas
Pipeline makees the vibrations of vertical direction, and the fine particle in flue gas during vibrations is sent out with flue gas in bend pipe of turning back simultaneously
Raw disturbance, collides so as to promote particulate matter in bend pipe of turning back, and promotes fine particle generation reunion to grow up, this
Rolled over bending pipe increases the complexity that particle is moved in bend pipe of turning back simultaneously during vibrations, promotes particulate matter more
Easily enter among reservoir block 210.Electromagnetic shaker 202 is provided with capture unit of turning back 200, electromagnetic shaker 202 can promote to roll over
Bending pipe shakes.
A kind of Ore Sintering Process flue gas PM of the present embodiment10/2.5Selective discharge-reducing method, step is as follows：Selection is burnt
The knot rear portion bellows 412 of chassis 410, first carry out rough dedusting by the flue gas removing dust device 420 in rear portion bellows 412, and deduster 420 can
First to remove larger particulate matter, reunion capturing device can be exclusively used in the removal of the fine particle in flue gas, so as to improve
The specific aim of fine particle emission reduction.Flue gas in rear portion bellows 412 is introduced into reunion capturing device, fine in flue gas
Grain thing trapping is agglomerated in reunion capturing device, in reunion capturing device to flue gas in spray into agglomerator, fine particle
It is sufficiently mixed with agglomerator, agglomerator droplet is sufficiently mixed and reunites with flue gas grows up, in reunion capturing device by flue gas
Subparticle is reunited, trapping removal, and the flue gas after purification is introduced the flue collector 450 of pallet 410 by pipeline again；Wherein reunite
Capturing device is as follows to the reunion capture method of fine particle：
Step one, fine particle are reunited
Flue gas enters reunion capturing device, in reunion capturing device to flue gas in spray into agglomerator, fine particle with
Agglomerator is sufficiently mixed, and agglomerator droplet is sufficiently mixed and reunites with flue gas grows up；Describe in detail as follows：
A, flue gas enter particle agglomeration room 104, and agglomerator droplet is sprayed into the top of particle agglomeration room 104 is to flue gas,
And the flow direction of the injection direction of agglomerator droplet and flue gas is conversely, flue gas is under the effect of the flow-disturbing of turbulence columns 102, subparticle
